I didn't plan on pointing to more resources quite yet, but the sale ends in 10/31/07. Desiring God is showing generosity once again. They are selling Piper's latest book for $5. Its called 'The Future of Justification: A Response to N.T. Wright.' It releases in early November. This book won't be for everyone, but if you are aware of or interested in the current justification controversy, this will be one to add to your library. If not, you may just want to save your $5. Here is a 7 part interview with Piper concerning the book.
